Agree on hand 1 for sure, thought about this more last night. Even though his range includes 9X or weaker that might call the 1/2 pot bet, it has a lot of Ax hands that call a bigger bet, and I think the value from them probably make up for him folding weaker ones.

That K giving worse 2p a lot is a perfect example of what I'm talking about. Previously I just think "shit, 4 straight on board I'm either slightly ahead but he folds or way behind" instead of really thinking through his ranges and realising that he had a lot of P+draw on flop that now have 2P and will call.
